It works very well on my sub-basin, 03060101.  I worry about the
length of the ways though.  If anyone downloads an area adjacent to
the lakes in my area, they would be pulling in a rather large way, in
this case a closed way.  Should large bodies of water be segmented and
be joined using a multipolygon relation?

Also, for the "holes" created by islands will those be easy to add in
later when the script is updated to handle them?

Cheers,

Adam
